CycleTrader/Rock River/Yamaha

In 2009, after the first Rock River Powersports-supported amateur rider turned pro, Rock River owner Mike DuClos felt that something needed to be done to continue supporting his former team rider. As a result, the Rock River Racing pro team was created as a stepping stone for amateur riders who were joining the professional ranks. The following year, Rock River Racing partnered with Yamaha Motor USA to support riders and also provide trackside parts and service at all pro events for Yamaha racers.

In November 2013, CycleTrader joined the team as an official title sponsor, and the team underwent a total re-branding to position themselves as one of the leading teams in AMA Supercross and Motocross racing.

For 2018, Mike DuClos and team manager Christina Denny lead the team with Bradley Taft (#53) and Brandon Hartranft (#114) both aboard Yamaha YZ250F machines in 250SX and Alex Ray (#91) aboard a Yamaha YZ450F in 450SX.

Rock River also continues to operate Yamaha’s successful “Pro Parts” program, offering emergency OEM parts at a discount to all Yamaha racers at all Supercross and Motocross events, including the Monster Energy Cup.
